Investigators believe the fight started because someone in Ynfante’s group had looked at a girl who was with the two men now sought by police.

Fullerton police provided this still image of surveillance footage that captured an assault in the 100 block of North Harbor Boulevard on Aug. 23, 2014. Police asked for the public's help in identifying two men who injured three others.

One of the two men police were searching for was described as white, about 6 feet tall, 210 pounds, in his mid-20s, with a muscular build, brown eyes, a deep voice and brown, spiked hair.

He was clean shaven and wearing a white long-sleeve, collared button-down shirt during the assault.

The second man was described as a white or light-skinned Hispanic, 5 foot 8 inches, 180 pounds, in his mid-20s, with a clean shave. He was wearing a red T-shirt with unknown lettering.

“Suspect No. 2 has a very distinctive set of lines that are razored into the sides of his head,” Hamel said.

A family member confirmed this Facebook photo shows Irvin Ynfante.

The woman, who police said was possibly the first man’s girlfriend, was wearing a white tank top and had blond hair.

Friends and family members have set up a GoFundMe account to help with Ynfante’s medical expenses.

“He is going to need medical attention for a while and we want to help his family out through this difficult time,” a message on the account page read.

Updates on Ynfante’s condition were also being posted on a Facebook page Justice for Irvin set up on his behalf.
